this purpose upon the s rtaee m. The lube 1s now partiallyv ininiaf'et, and accurately seatniold is Closed. Air or other fluid under pressure is admitted to the interior el the tube through the valve stern and the tubeY will be vulcanized as is understood by those skilled in the art. The forni of the shell may be Varied, but the substantial hexagonal Cross-section is preferred, as it aii'ortls. a very strong construction and seats readilyv within the inold Cavity.

Vilhat is Claimed is:

l. An apparatus for curing inner tubes Yunder internal pressure, comprising two ehamherecl mold sections, and a removable Circular shell loeatetl between said sections, seid shell being substantially hexagonal in oross-section with one side antix a portion ot a second side removed, three sides et the shell being seated within one inoitl section and the remainder of the shell being seated within the other inoltl section`r the last named section having a protruding rio adapted to eomplete 'the tube earity.

2, n n apparatus `tor enringinlns initier internal pres are, comprising tn-e Chanih -grerl nioltl seetions anri a circular renier/aine shell having an opening about ons side thereofnv through which trie tnhe may he inserteth the she-il being adapted to lie within one nioiti section, the other inoltl section haring a projeeting rib adapted to lit within said opening to Complete the mol@ cavity.-

B. in an apparatus for the uses and purposes set forth, a sectional inold, and 'removable sheii therein for receiving an inner tube, said, shell being open at one side to permit. the insertion of a tube therein, one of said molti sections having a projecting portioljifatlaptetl to tit within saifl opening to complete the tube molding Cavity.

4i. in an apparatus for the uses anti purposes set vforth, sectional inold, and a res movable shell 'therein for reeiving inier tube, saicl shell being open ,i approximately oneqnarter Q tion to permit the insertion et a in, one of said inolel sections har jeeting portion adapted to .tit 2v opening to complete the tube inoitiing curity.

5. ln an apparatus for the uses enti purposes set forth,v s .sectional moitiey and a removable shell for receiving an inner tuoe and adapted to lie within one section, said shell being open at one side but provided 6o with a portion about its inner circumference whieh projects above the ini'ieri'nost one about the tube, said projecting portion in ing recessed for the reception ot a faire Stein.

6. ln an apparatus Ator the uses and pui poses forth, a sectional inoid, and movable shell vfor reeeiving an inner tn'he and adapted to lie Within one section, seid shell being open along' one si but ororitieti -o with portions which project abo low its inner and enter eircom arenees speetirely, the other section o f ing a projecting portion saitl opening anti eonnlilete cavityu "i". .in an apparatus tor t poses set forth, a see movable shell for anti adapted to lie shell hef Sii tion being notehed tor the ai, ,iission oi' a valve stein, and the other section h projecting rib adapted to eiose within the shell and. a filler said notch when the sections are TJ geti'ier.
